5 Steps to Restoring Oxidized Gelcoat
Wash and Remove Surface Dirt and Debris. The first step to removing oxidation and giving your boat a new look entails washing and eliminating every form of surface dirt.
To help to restore the color, shine and appearance of your boat, choose a gelcoat restorer. Gelcoat restorers are suitable for fiberglass (GRP) gelcoats and can help to give long lasting effects, wetting the pigment to restore a strong and vibrant color and shine.
Can boat gelcoat be repaired?
Wet-sand the cured gelcoat with 320-grit wet/dry paper on a soft sanding block. Confining work to the immediate repair area, continue wet-sanding with 600-grit paper until nearly even with surrounding gelcoat. Finish wet-sanding with 1,000-grit paper; then buff out with rubbing compound followed by a coat of wax.
When hiring a professional to do re-gel coating, remember that they are doing a job appraisal at a rate. The typical price will be $300 to $500 per foot if the hull is in excellent condition without significant damage.

Can you gelcoat over gelcoat?
Can You Spray Gelcoat Over Gelcoat? The short answer’s yes. But first, make sure the surface is free from dirt and debris. Using the window frame analogy again, you wouldn’t apply new paint over old paint without preparing the surface.
How long does gelcoat last on a boat?
Gel coat paint for boats can last up to two decades before needing major repair work, while marine paint will typically need one or more major repairs within ten years. However, repairing and refinishing gel coat is much more labor-intensive than with marine paint.
How much does it cost to reseal a boat?
Expect to pay anywhere between $150 to $250 per foot (and up) to have a hull painted with any sort of two-part paint, such as Awlgrip, Alexseal, or Imron. You’ll pay approximately the same price to have the decks done, although the per-foot rate can be a bit higher because of the detail work involved.

Repairing Minor Gelcoat Cracks
Use a rotary tool or scraping tool to open the crack into a “V” shape.
After removing the dust, you can fill the crack with G/flex® 655, Six10® or WEST SYSTEM 105 Epoxy Resin®/20X Hardener thickened with 406 Colloidal Silica Adhesive Filler.
Often very minor scratches and scrapes can be wet-sanded away. Try using 400-grit wet-sanding sandpaper, followed by 600-grit. Always use a sanding block so you don’t over-sand one particular spot, and use a gentle, circular motion. If the scuff or scratch disappears, great.
How do you get deep scratches out of gelcoat?
Surface scratches can be buffed out of gelcoat with polishing compound, but deep scratches must be filled. When the gelcoat surrounding a scratch is in good condition, the filler of choice is gelcoat paste, which provides both filler and finish in a single application — but not a single step.
How do I bring the shine back to gelcoat?
How do you fix deep scratches in gel coat?
Usually, a simple wet-sand and buff can bring back the original glow of the gelcoat. If the scratch is a bit deeper, start off by dry sanding with 180-grit sandpaper.Once the scratch appears to be fading, gradually move to a 320-grit, followed by a 500-grit, and finally a 1000-grit sandpaper.
Can gelcoat be buffed?
If the gelcoat starts to look transparent, stop. After the surface has been compounded, polish it, then coat it with wax and buff it. Providing the gelcoat has an adequate thickness — your boat might have been compounded previously — this process will restore the shine to fiberglass in almost any condition.
How do you fill a gel coat with scratches?
Can you use rubbing compound on gelcoat?
All rubbing compounds are abrasive, and if not used properly, they can scratch and damage gelcoat and painted surfaces. There are dozens of rubbing compounds on the market, so to narrow the test field, we focused on only coarse and medium-coarse products.
They are excellent for cleaning dull gel coat to remove fine contaminants before wet sanding steps on the way to restore the gel coat’s shine by buffing. They wear out fast, but they are relatively cheap.
What does acetone do to gelcoat?
Acetone should not hurt gelcoat but will strip off any wax and may make the gelcoat look calky. Acetone is an organic solvent and probably would not be very good at removing metallic stains. A little diluted hydrochloric acid will usually remove metal stains and dissolve calcium salts.
How do you remove heavy oxidation from gelcoat?
The use of marine grade formulas such as Crush Liquid Compound or Riptide Liquid Compound will quickly and effectively remove oxidation from the surface exposing fresh gel coat and fiberglass.
Can oxidation be buffed out?
Light-to-moderate oxidation can be removed with polishing compounds, while heavy oxidation requires a rubbing compound. Apply the compound gently to a small area, work it into the paint and remove it quickly, repeating until all signs of oxidation are gone.
